Stainless Steel 3.5 Inch SelfLocking Cattle Ring

Size: 3.5 inch outer diameter (89 mm), engineered for adult cattle nose anatomy — neither too tight nor overly loose, allowing natural breathing and head carriage while providing effective leverage. Material: Solid 304-grade stainless steel — tensile strength sufficient to resist bending during forceful animal movement; surface hardness prevents scratching or gouging during contact with metal gates or handling systems. Weight: ~120 g — contributes to stable positioning without adding undue load on nasal tissue. The self-locking feature relies on a dual-cam engagement system machined directly into the ring body — no welds, rivets, or secondary components — resulting in a single-piece structure with no failure points. Closure is tactile and audible, confirming secure engagement before release is attempted. Performance remains unaffected by mud, manure residue, or light frost accumulation. Common applications include routine herd health monitoring, compulsory ear tag application under DEFRA guidelines, pre-sale inspections, and movement through narrow gateways or weighbridge setups — all scenarios where momentary, hands-free control improves efficiency and reduces physical strain on handlers.
